Module 2: Aggregation

Figure 2: The Figure above illustrates our circuit for Module 2 (Aggregation). The p(sal) Promoter BBa_K228004 (modified - see below) which triggers the Aggregation circuit is turned on when bound by activated NahR protein from Module 1. Once the p(sal) promoter is activated, it drives expression of the Curli Cluster of genes (BBa_K540000). The individuals genes of the cluster are shown radiating from BBa_K540000.

Modified BBa_K228004: The BBa_K228004 BioBrick must be modified as it combines both the NahR protein and the p(sal) promoter. We wish to seperate these.

Module 3: Plastic Degradation

Figure 3: The image above shows the circuit for Module 3 (Degradation). The Constitutive Promoter (BBa_J23119) drives constant expression of the Laccase BioBrick (BBa_K729002). The Laccase gene we intend to use originates from a particular bacterial strain, and is capable of Polyethylene Degradation.
